Introduction to Zhang Fei's Drum Platform: On the top of Xiling Mountain in Sanyou Cave facing the river, there is a cylindrical stone peak with a small platform on it, which is the famous "Zhang Fei's Drum Platform". According to local chronicles, during the Three Kingdoms period, Zhang Fei, a fierce general of the Shu Han Dynasty, used to beat drums here to supervise the training of soldiers when he was the prefect of Yidu County (now Yichang).
